Tehran (AP) – Iranian President Mahmoud Ahmadinejad said Sunday Iran will file a complaint to international bodies over the deadly mosque bombing by an insurgent group he says the U.S. supports.

The twin suicide bombings of a mosque in southeast Iran killed 28 people Thursday night, in an attack claimed by the Jundallah insurgent group as revenge for the execution of its leader by Iranian authorities in June.

Ahmadinejad did not specify if the complaint would be specifically against the U.S., but he did tell state TV that America supported the bombings.

"If (President Barack) Obama is not aware of actions by American forces, we tell him that American troops based in Afghanistan and Pakistan support these actions," he said referring to the bombings. "Yet, the American president sends a condolence message."
